Configuring Tunnel allow-remote
Decapsulation
You can configure an IPv4 or IPV6 address or prefix whose tunneled packet will be accepted for
decapsulation.
• If no allow-remote entries are configured, then tunneled packets from any remote peer address will be
accepted.
• Upto eight allow-remote entries can be configured on any particular multipoint receive-only tunnel.
The following sample configuration shows how to configure a tunnel allow-remote address.
Dell(conf)#interface tunnel 1
Dell(conf-if-tu-1)#ipv6 address 1abd::1/64
Dell(conf-if-tu-1)#ip address 1.1.1.1/24
Dell(conf-if-tu-1)#tunnel source 40.1.1.1
Dell(conf-if-tu-1)#tunnel mode ipip decapsulate-any
Dell(conf-if-tu-1)#tunnel allow-remote 40.1.1.2
Dell(conf-if-tu-1)#no shutdown
Dell(conf-if-tu-1)#show config
!
interface Tunnel 1
ip address 1.1.1.1/24
ipv6 address 1abd::1/64
tunnel source 40.1.1.1
tunnel allow-remote 40.1.1.2
